POWER SUPPLY FOR A LIGHT DEVICE OF A MOTOR VEHICLE HAVING A PLURALITY OF OUTPUTS

The invention proposes a control circuit for the power supply of a plurality of groups of light sources, preferably of the light-emitting diode type, which perform a plurality of lighting functions of a motor vehicle. The device is noteworthy in that it allows for the provision of a primary voltage output and several secondary outputs at high voltages, corresponding to the power supply requirements of the different groups of light sources, by means of a single switching converter circuit.
